When there is more demand for my services than I feel like handling, I can raise my rates. If a customer doesn't like it, they can find someone else. They don't need me. However, when your business sells a necessity (like public transportation or runs a hospital) don't expect your customers to understand that your decision to charge them much higher prices during an emergency is simply done "to better allocate a scarce resource". Keeping poor people from using all the scarce resources is probably not the best thing to do if you want repeat business.
